0F I-IOLLYDALE, CALIFORNIA TILE BOARD Application filed April 7, 1930.Serial No. 442,114.

This invention relates to tile board, and has for its object theprovision of an improved method and means for forming and mounting tileblocks on suitable sheets of stiff material such as ply wood, plasterboard, and the like.

It is an object of this invention to provide a tile board formed of astiff and substantially non-expansible back having one surface of saidback covered with wire mesh,

screen, metal lath, or the like, to which is distort, warp, expand orcontract the assembled board will be offset or compensated for by theinterposition of the carrying material between the back and the tilefacing.

In the accompanying drawing I have shown a preferred embodiment of myinvenn tion in which the figure is a. perspective view of a section oftile board embodying my improvements.

In said drawing a suitable back 1 is provided, which may be formed of aplurality of plies 2, 3 and 4 of wood,which are arranged with the grainof alternate sheets at right angles to the grain of the other sheets.Such a backing is substantially non-eXpansible. In lieu of the wood backl I may use plaster board or composition lath or any other suitable andsutliciently non-expansible material.

To a face of the back 1 I apply a metallic cushioning member 5 which maybe formed of wire mesh afiXedvto the back l by means of staples 6, or byother suitable means. In lieu of the wire rmesh I may employ perfo;rated material, expanded metal lath, or any other suitable light weightmaterial. The wire mesh, however, is deemed to be most suitable for thepurposes ofy my invention.

The member 5 forms a carrier and atthe same time a cushion for thefacing of tile, and is adapted to be covered bya coating of asemiplastic cement 7 which fills the interstices between the wires ofthe mesh and underlies certain portions of the mesh, thus forming asmooth adhesive coat outwardly lof the wire mesh 5. An example of saidsemiplastic cement 7 may comprise a-composition of asphaltum, sal soda,marble dust and water. To this coat a facing 8 of tile lis applied bypressure or otherwise. The blocks of tile 8 are pointed as at 9 in theusualqmanner and by the usual means, and the arrangement of the tileblocks is such as to produce ornamental and decorative effects.

It will be observed that the coating of cement 7 and the eXpansible wiremesh5 form an expansible cushion between the substantially stiff andnon-expansible lback ll and the facing of tile8, so that any tendency towarp, distort, expand or contract is compensated for by the intermediatecushion, thus reventing damage to the tile facing. I pre er to use acement which may combine certain vegetable and mineral ingredients insuch manner that a maximum tenacity and a suHcient resiliency will beprovided, and which will at the same time provide against the entranceof moisture and bacteria. By semi-plastic cement is meant a compositionwhich when set and dry will not be brittle, but will retain asubstantial amount of resiliency so as to compensate for the expansionand contraction of the mesh carrier 5. For instance, assuming that theback l is non-eXpansible, it is apparent that the wire mesh 5 is highlyeX- pansible due to differences of temperature. The coating 7 should besufficiently resilient tol compensate for the expansion of the Wire mesh5 without cracking or pulling the tile blocks 8 apart.

It Will be observed that I have provided a substantially economicalmethod and means for producing tile board in sheets or panels ofsuitable size whereby the erection of the same in a building may bequickly and economically done as compared to other methods.

Vhile ply Wood or composition panels, as at l, are substantially stifand proof against warping and distortion, I may provide any suitablemeans on the backs of said panel for additionally stiifening the same,as taught by others in the art.

What I claim is:

1. A Wall structure comprising a panel l formed of a non-expansibleback, an eXpansible metallic sheet of material applied to a facethereof, a semi-plastic cement applied oversaid metallic sheet and afacing of tile attached to said cement.

2. A Wall structure comprising a panel formed of a stiff back, a sheetof Wire mesh attached to a surface of said back, a semiplastic cementapplied over said Wire mesh and a tile facing attached to said cement.

3. A structure formed of separate panels having non-expansible backs,sheets of apertured metallicmaterial attached to the surfaces of saidbacks, a coating of semi-plastic cement applied over said metallicmaterial and tile facings attached to said cement. p

4. A structure comprising a panel formed of a stiff back, an eXpansiblemetallic cushion attachedv to a surface of said back, a semiplasticcement applied over said cushion and a tile facing adhesively applied tosaid cement.l

5. 4A. structure comprising a panel formed of a non-expansible back, aneXpansible metallic cushion attached to a surface of said back, asemi-plastic cement covering said back and said cushion, and a tilefacing covering said cement.
